There’s an ongoing symbiosis between two peculiar populations of (mostly) young and female Tumblr users: those who post fashion-inspiration pics from Harajuku alongside glitchy animated GIF art and vintage photos of Aaliyah and Britney, and those who belong to the burgeoning pack of musicians hoping to emulate those singers’ pop success while maintaining at least a hint of art-damaged weirdness. British singer Charli XCX is one of the latter crew’s most notable personalities. Her recent contribution to Icona Pop’s surprise hit “I Love It” helped earn her some stateside popularity (though not as much as she’s enjoyed at home for a while now), and she’s just followed it up with the brand-new True Romance (Iamsound), which combines edgy production and the unmistakable influence of a past generation of torchy UK pop singers such as Sinead O’Connor and T’Pau’s Carol Decker. —Miles RaymerMarina & the Diamonds headline.
